12AN 3/4NPT Pipe Plug Hex Head Black 2/pkg

The 12AN 3/4NPT Pipe Plug Hex Head Black 2/pkg from REDHORSE PERFORMANCE is a precision-engineered hydraulic fitting designed for high-pressure fluid systems where port closure and sealing integrity are critical. Ideal for race engines, custom fuel systems, and professional automotive hydraulic installations, this plug prevents fluid leakage while maintaining system pressure and preventing contamination at unused connection points. Whether you're building a performance vehicle or servicing industrial hydraulic equipment, a reliable port plug is essential to system longevity and safety.

Constructed from aluminum and finished in black anodized coating, this 932 Series plug delivers corrosion resistance and a professional appearance in demanding environments. The 3/4 inch NPT (National Pipe Thread) connection ensures compatibility with standard hydraulic and pneumatic systems, while the hex head design enables secure installation and removal using standard wrenches or hex sockets. The tapered NPT thread provides a self-sealing mechanical bond that eliminates the need for thread sealant tape in most applications, ensuring a tight, leak-free connection that withstands vibration and thermal cycling.

This two-pack configuration serves technicians, fabricators, and enthusiasts who maintain multiple systems or require spare plugs for future modifications. The compact 2.8 x 1.1 x 3.8 inch footprint and lightweight 0.07 lb construction make these plugs easy to store and transport. Compatible with any system using 3/4 NPT female ports—including fuel rails, brake line manifolds, transmission coolers, and custom plumbing—this REDHORSE fitting delivers OEM-equivalent quality at a practical price point for serious builders and professional shops.
